His father Joseph Max Fleming and wife Margaret lived in Oelwein and then Waterloo so Joseph Allan Fleming was born in Fayette Co or Black Hawk Co in 1951.

Can someone check at the courthouse to see if he was indeed born in Fayette County and if so what is the complete birth date.

Is this person still alive?

I checked the SSDI and see that the person you're researching passed away earlier this year.
